Deactivation of a Au/CeO2–Co3O4 catalyst during CO preferential oxidation i…
Abstract. The origins of the deactivation of a Au/CeO2–Co3O4 catalyst during CO preferential oxidation (PROX) are investigated in detail by means of high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), temperature-programmed reduction of hydrogen (H2-TPR), temperature-programmed oxidation of oxygen (O2-TPO), and diffuse …

Preparation and properties of Ni-doped ZnO rod arrays from aqueous solution
Abstract. Ni-doped ZnO rod arrays were successfully prepared on glass substrate from the aqueous solution at a temperature of 80 ◦C. The densities, diameters, and lengths of the rods can easily be well controlled through the concentrations of dopants, and the dopant Ni ions were incorporated into the wurtzitestructure of ZnO crystal. Room temperature photoluminescence spectrum of rod arra…

Comparative study on electrochemical degradation of 2,4-dichlorophenol by dif…
Abstract. Pd/C catalysts used for the Pd/C gas-diffusion cathodes were prepared by the hydrogen gas and/or formaldehyde reduction, and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and cyclic voltammetry (CV). The electrochemical degradation of 2,4-dichlorophenol was investigated in a diaphragm electrolysis system,…

Simultaneous production of hydrogen and multi-walled carbon nanotubes by etha…
Abstract. Ethanol decomposition was studied over Ni/Al2O3 catalysts with different Ni loadings (10–90 mol%) at temperatures between 500 and 800 oC to produce hydrogen and multi-walled carbon nanotubes (MWCNTs) at the same time. The hydrogen production increased with increasing temperature and Ni loadings. However, both the quality and the quantity of the nanotubes formed at the relatively…

Co-production of hydrogen and multi-wall carbon nanotubes from ethanol decomp…
Abstract. The co-production of hydrogen and carbon nanotubes (CNTs) from the decomposition of ethanol over Fe/ Al2O3 at different temperatures and feeding rates of ethanol was investigated systematically. The results indicated that Fe/Al2O3 was a quite active catalyst for the co-production of hydrogen and CNTs and that its activity and stability depended strongly on the Fe loading. Among al…

Effects of metal content on activity and stability of Ni-Co bimetallic cataly…
Abstract Ni-Co bimetallic catalyst with a general formula of Ni-Co-Al-Mg-O prepared using coprecipitation has shown excellent stability and high activity for CO2 reforming of CH4 in our previous research. This paper focuses on the effects of Ni-Co content of the catalyst, attempting to avoid carbon formation on the catalyst. Catalyst samples with Ni and Co loadings ranging between 1.83 and 14.…

The utilization of acid-tolerant bacteria on ethanol production from kitchen …
Abstract In order to achieve ethanol production from kitchen garbage under non-sterilized fermentation, the acidtolerant Zymomonas mobilis named GZNS1 was selected and applied in the fermentation system. Ethanol production from kitchen garbage under non-sterilized fermentation with GZNS1 was proved to be feasible. The utilization of control strain and acid-tolerant strain under different con…

Kinetic Studies of Carbon Dioxide Reforming of Methane over Ni-Co/Al-Mg-O Bim…
The kinetics of CO2 reforming with CH4 over a Ni-Co/Al-Mg-O bimetallic catalyst was investigated in a fixed bed reactor at a temperature range of 650-750 °C and the partial pressures of CO2 and CH4 ranging from 30 to 190 kPa. Owing to the simultaneous occurrence of the CO2 reforming reaction and the reverse water-gas shift reaction (RWGS) in the system, the apparent activation energies with…

Investigation on Photophysical Properties of D–p–A–p–D-Type Fluorenon…
The effects of p-spacer and electron donor groups on the photophysical behaviors of fluorenone-based linear conjugated oligomers have been systemically investigated. Solvent-dependent steady-state measurements exhibit that the fluorene vinylene (FV) spacer and the electron-donating ability of donor group are able to modulate the spectral features of oligomers and the fluorescence quantum yield …

Investigation on “Excimer” Formation Mechanism of Linear Oligofluorenes-F…
We study the photophysical characters of two oligofluorenesfunctionalized anthracenes molecules with different fluorinevinylene (FV) units, which exhibits that “excimer” state appears in the solution after photoexcitation. The dynamic data shows that two mechanisms are responsible for the generation of “excimer”. The fast one is controlled by the arene-arene interaction between molecule…
